AUTOMATIC WEIGHING APPARATUS.

To all whom t may concern:

' Be it known'that I, JOLLY L. Monats, a citizen of the United States, residing at Grafton, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Automatic lVeighingApparatus; and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference Vbeing had to the accompanying drawings, andto the letters and figures of reference marked thereon, which form a part of this specification. j

This invention relates to new 'and useful improvementsin weighing scales and especially in the provision of automatic means for weighing commodities and for cutting off the supplyv when the desired weight is indicated by the scales.

The invention comprises various details of construction,combinations and arrangements of arts which will be hereinafter fully described, shown inthe accompanying drawings and then speciiically defined in the appended claims.

I illustrate my invention in the accompanying drawings, in which:

Figure 1 is a side elevation of the appavratus with the exit' openingl of the hopper closed. i Fig. 2 is a detail view of the apparatus taken in a plane at right angles to Fig. 1.

Fig.`3 is a central vertical sectionalview showing the slide regulating the exity opening held open.

Fig. 4 is a view showing the slide closed. Fig. 5 is a bottom plan view. Reference now being had to the details of the drawings by numeral, 1l designates the base of the apparatus, and 2 vertical portions of a standard, which have a transverse, horizontally disposed portion 3 and which standard is securely fastened and braced to the bottom or base through the medium of the bars 4. YA hopper 5 isk secured to said standard and has an exit opening 6 in the lowest part of its tapering bottom, as shown clearly in Fig. 3 of the drawings. A sliding closure 7 is mounted to have a movement between the flange members 8 upon the under side of the hopper and said slide is guided in its longitudinal movements by the contracted por- Specicaton of Letters Patent. Patented DML 11, 1917 Application led May 25, 1917. Serial No. 171,002. Y

tion 9A thereof moving between the strap 10 and the inclined face of the bottom of the hopper, as shown inFig. `5 of the drawings, the outer end of the contracted portion of said sliding closure being bent at an anf' gle at 11, and 12 is a slot formed in the shank portion of the slot and is adapted to receive one end of the trigger 13 which is mounted upon a pivot 14 mounted in the bracket member 15, secured to the side of the hopper. Said trigger, it will be noted, has a iinger 16 projecting therefrom and which is adapted to be positioned in the pathV of the lug 17 fastened to the pivotal, bail-shaped member 18, which latter is pivotally mountedy upon the pin 19. Oneend of the trigger is adapted to engage the slot 12 inthe manner shown in Fig. 3 of the drawings for the purpose of holding the sliding closure 7 in an open positionagainst the-tension of the coiled spring 20, which mounted upon the sliding closureintermediate the latter and a strap 26, shown vclearly in Fig. 5 of the drawings, and the outer ends of the wire forming said bail-shaped member 25 project beyond the end` of the rectangular-outlined portion of said bailshaped member and are pivotally connected to a pin 27 projecting laterally from the inner ends of the screw 28, which is fastened to the plate 29, through the medium of the pivot 30, with the hopper. Said screw 28 serves as a means for pushing vin upon the bail-shaped member for the purpose of throwing the slide to an open posi'- by one end of the trigger 13, in readiness to be sprung as the lug 17, meunted'upon the bailshaped scale member 18. It will be noted upon reference to Fig. 1 of the drawings that one arm 35 of the bail-shaped member 18 has a scale thereon and upon which a weighted member 36 is adjustably held.

Pivotally mounted upon the pins 37, secured to the bail-shaped member 18, are the swinging arms 39 which support the plattion, the same being automatically engaged 4v`10o form 40 upon which a lreceptacle il may be placed underneath the exit end of the hopper.

In operation, the commodity to be 'measured and which is placed within the hopper is allowed to make exit through the opening 16 when the sliding closure is withdrawn to the position shown in Fig. 3 of the drawings. l/V hen a sufficient amount of .the com.- modity being measured enters the receptacle, the Vplatform will tilt and, as ,the lug i17 comes in contact with the trigger 13, it wil-l tilt the same, releasing its ,end from the slot the sliding closure and the coiled spring will throw the closure to the position shown in lFig. i of the drawings, thus automatically cutting off the supply. For resetting the iclosure in an open or retracted position, it may be done either through the medium of the hooked end 171 or the screw 28 which may be pushed inward, causing the bail-,shaped member to thro-W the Slide Ahack to its YSet posit-ion. By the provision of the automatic weighing device shown and described, it will vloe noted that a simple and .eiiicient means is provided whereby the commodity may be automatically weighed and the supply cut Aoff when the weight tilts the scale.

lVhat I claim to be new is '1. An apparatus for automatically weigh,- ing commodities, comprising a hopper with an eX-it opening in the bottom thereof, a sliding, ,spring-pressed -closure regulating the exit opening, a trigger mounted upon the hopper and adapted to engage and hold the sliding closure retracted, a scale beam and weighingplatform supported thereby, means upon the beam for tilting the trigger to disengage the same from kthe sliding closure, a member pivoted to said slid-ing closure Aand having swinging pivotal connection with the hopper.

2. An apparatus `for automatically weighing commodities, ,Comprising u hopper with an exit opening in the bottom thereof, a Sliding spring-pressed closure regulating the `exit opening, a trigger mounted upon the hopper and adapted to engage and hold the sliding closure retracted, a scale beam and weighing platform supported thereby, means ul-pon the beam for tilting the trigger to dis.- engage the saine lfrom the sliding closure, a bail-shaped member pivoted to said closure having projecting ends, and a `pivotal plate mounted upon the hopper and yhaving pivotal connection with said projecting ends of the bail-shaped member.

8. An automatic weighing apparatus comprising a hopper with an exit opening in the bottom, a -iveig'hing scale beam pivotally mounted upon the hopper, a platform having 'pivotal arms connected to said egale beam, a springpressed, sliding closure, guideways in which said closure is mounted, a contracted portion of the latter .heilig provided with a slot, a trigger pivotally mounted upon .the hopper and .adapted to engage eaiclelot, and lug upon .the scale heaui ele- Signed to Contact with .said .trigger vto release theA Same from the elieling ,eiloeulrevi. An automatic .weighing apparatus corr` pri-sing .a hopper with an eiit opening iu the bottom, a weighing rscale Vbeam pivotal'ly inouuter'l upon .the hopper, ple.tiorru hevng pivotal arms oohueeted to ,Said .scale beam, a Spriug-preeeed, :sliding eloeure, guidewaye ih Awhioh `saisi oloeure 'is' mounted,

contracted port-.ion of the latter being provided with a slot, a trigger iuotally niounted upon the hopper ,and `arfipted to engage Suid Slot, a flug 'projecting from .the ,shank portion of the sliding closure, a strap for guiding the latter and against which Strap .Said lug .is adepteu to Contact to limit the movement of the ysliding ,closure in one .,direction.

5. A11 automatic weighing apparatus .cour prising a hopper with an Yexit fopen-ing in the lower iend thereof, guideways upon the bottom of the hopper, a sliding closure IHOYab'le between the guideways, Vfingers projecting from -said sliding closure, va strap secured to the bottom of the hopper having slotted luge through Wheh Said flug-ere move, springs bearing against said lugs and portionsof the sliding closure, a trigger adapted to engage kand hold the Asliding kclosure retraeted,H aeeale beam pivotally mounted upon the hopper, a lug eeeured .to Said beam, adapted to' tilt the trigger and .throw the same out of engagement with the sliding closure, and a platform pivotally supported upon the scale ,beam.
